Refueling stations (called a benzinci or a petrol istasiyonu) all over Turkey usually sell two octane grades of unleaded gasoline (benzin), and diesel (dizel or mazot). Some also care Euro deisel. At a Turkish petrol station, there will usually be a market where you can buy drinks, snacks, and auto accessories. Some have automatic car washes. At others, you can ask an attendant to wash your car for a small fee, and even vacuum clean the interior.
All Turkish petrol stations are full-service. An attendant will come out to ask you what you want, refill your car, and usually clean the windshield. You can also ask him to check the oil and air pressure in your tires. A small tip for these additional services is customary.
If you are driving for long distances or plan to use a lot of fuel, you can rent a car with an engine which runs on diesel or Euro diesel fuel. While the cost of renting one of these cars is higher, the fuel is much cheaper, so paying more for a more efficient engine may save you money in the long run. While practically all petrol stations in Turkey have diesel, not all of them sell Euro diesel. You may have to visit a few stations to find one that sells it. Euro diesel cars (like diesel cars) have a specially-designed receptacle which will only accept a Euro diesel nozzle.
Because of the high cost of petrol in Turkey, it isn't a good idea to rent a car for long, cross-country trips, unless you plan to make a lot of sight-seeing stops along the way. A better alternative is to take a bus or a flight for the long portions of your trip, then rent a car for local excursions.
